Question What are the supported Layer 2 interworking stitching configurations? Answer These are the stitching options supported in Junos OS Release 9.3 and later: Layer 2 circuit into Layer 2 VPN NOTE: In Junos OS Release 9.4 and later, you can use an iw interface instead of an lt interface for this purpose.

Question What is the solution for interprovider Option B connection between LDP-based Layer 2 circuits and BGP-based Layer 2 VPNs? Answer As of Junos OS Release 9.3 and later, Layer 2 circuits with interworking iw0 interfaces can be manually stitched. If dynamic signaling is needed, use FEC 129 multisegment pseudowires if you are not using BGP-based Layer 2 VPNs. In Junos OS Release 11.2 and later, FEC 129 is supported.

Question Can a Layer 2 circuit be terminated into VPLS?...For more information, click Layer 2 VPNs and VPLS Feature Guide
The most common MPLS connectivity services include: Virtual Private LAN Service (VPLS) Layer 3 virtual private networks (VPNs) Layer 2 circuits and Layer 2 VPNs Layer 3 VPN service is a point-to-point Layer 3 VPN network built over the service provider’s MPLS transport network. This type of service is based on RFC 2547bis, BGP/MPLS IP VPNs . To ramp up on Layer 3 VPNs in Junos OS, click Layer 3 VPNs Feature Guide . This article provides answers to the most common questions about Layer 3 VPNs on Juniper Networks MX Series routers
You can port-mirror traffic from a Layer 2 VPN on MX Series routers for PE routers
Answer The following are the Juniper Networks solutions for Metro Ethernet Forum (MEF) 6.1 Ethernet services definitions: Ethernet private line (EPL) and Ethernet virtual private line (EVPL) are emulated by Juniper Networks Layer 2 circuit and Layer 2 VPN configurations
Answer Prior to Junos OS Release 10.3, indirect next hop is only supported for Layer 3 VPNs. However, in Junos OS Release 10.3 and later, a constraint of not allowing VPLS configuration when using indirect next hop for other services is removed
This applies to Layer 3 VPNs and VPLS point-to-multipoint LSPs...For more information, click Layer 2 VPNs and VPLS Feature Guide
Question What are the Junos OS solutions for terminating <password> Layer 2 circuits into VPLS? Answer On an MX Series router, 48 Layer 2 circuits can be terminated into a single VRF, per each tunnel PIC. In Junos OS, <password> Layer 2 circuits can be terminated into VPLS by using logical tunnel (lt) interfaces
